FLUID-MIXER.

To all om it may concern; r v

Be it known that I, Luc en H.-HANDY, a.

citizenof the United States, 'residingat Oakland,- in the county .ofAlameda and State of California, have invented certain new and usefulImprovements in- Fluid- Mixers for-Internal-Combustion Engines, of whichthe' following is a specification.

-My invention relates to an auxiliary-device for assisting thevaporization of the liquid fuel-supplied to an internal combustionengine. and for alterin the condition of the gaseous mixture formedsubsequent to such vaporization.

It is well known that the vaporization of the liquid-fuel effected bythe usual type 0f carburetor is imperfect, and that consider able liquidfuel, in a. more or less'hnely divided "condition, is heldin suspensionby the gaseous mixture ofv carbureted air, and thuscarried into theengine cylinder. This results in a substantial \vaste'of fuel, and a.consequent reduction in the efficiency of the engine. in fact, this lossof'fuel is of such importance that numerous means have been employedforassisting the carbureter-in its vaporizingfunction, and liy such meansthe vaporization of 'the'relatively more volatile .h"drocarhons. suchas'commerctial "asolene, .A ,5.

is'rei'idcred more complete. The use, how ever, in" variablespeedengines, of the heavier fuels, such as'kerosene and the petroleumproductknown as engine distillate,nece$i' tatcs thi- .cmployment.of special;devices to insure the proper a iori'/a\tion of the fuel, and the propermixing of'the "vapor thus formed with air, in order to provide ahomogeneous gaseous fuel of the greatest possili'le ctiicic-ncy.

The object of my invention, therefore, is

to provide an auxiliary device which may hr readily applicd to thecarburetor of an internal combustion engine, or at any pointintcrn'u-diatc the carburetor and the engine vlindcr, which i-aporizcsany liquid fuel held in suspension l') thc imperfectly carlan-ctcd air.and thoroughly mixes the gas so formed int a homogeneous fuel mixture,and which so, controls. the l'n'o mrtions' of thecoinpoaent elements ofsaid mixture, that a gaseous fuel of the greatest possible effiicncy issupplied to the engine; the primary object of the devicebeing to renderpracticable the use of liquid fuels of relatively low volatility. By theuse of such fuels, which contain greater heat value per Specification ofLctters letent.

unit of weight, and which sell at a lower cost than the so-called highergrade fuels, the cost of operation'of internal-combustion engines may bematerially-reduced.

T 0 this end-my' in vention-'consists-in the novel device which 1- shallhereinafter describe with reference to theaccompanying drawings, inwhich i Figure l is aside elevation of my device, illustrating thepreferred method=of application to the-intake pipe-0f an internale0mhustion engine.

The screens l0 are pri-ferahlv formed withsuccessively smaller meshes from the lowermostto theupperinost-of saidscreens.

A vertical passage 13', Figs. .4 and (i of the drawings, is formed inone-sideof'ithe shell 1. opening at its lower end into the interiorcvlindrica bore of. said shell below thelowermost of the screens 10, asseen in Fig. 6, and at its upper end communicating with a double endedhorizontal passage 1 Into one end i said passage l ljisscreu ed uT-headed fitting 16, Figs. 1, '2, 3' and 4,

In the form illustrated, I ha've shown-a three- \va vvalveafil in the pipe 32 leading to the fpr-irted control valve,25, andby means of;

Said tl'iice-w'ay valve 31 the air may be drawn from-the atmosphere,tllrough the opening 33,- or through-,the pip' 31 from the mainair'supply pipe 35, the ai'r' therein being pie-heated bypassing througha. jacket I 36 surrounding the eng neexhaust-pipe the operation "of indev ice, wjhen the gaseous fuel mixture passes. upwardthrough theseries; of screens, anyipz'irt-icles of liquid fuel held "infsuspensionare-brol 'u p by impinging against =the a strands of said screens, andthe mixture'is thus rendered more homogeneous lloreover, on account ofthe simultaneous operation of the ported air valve 25 'with thefuei'throttle who 3), and the shapeof the port .26 of said valve 12.),more -air is admitted thereby hen the throttlewvalve is fully open thanwhen the ,same is-fonly partially op'emand so the proportions-of air andhydrocarbon vapor in the fuel mixture are maintained in correctrelation.

The priming valve 20 is designed to be used bytheoperator, at will,toadinit'additionalliquid fuel to the intake pipe, to rovide a mixturerich in hydrocarbons, w ich is sometimes'desirable, as for example instarting the engine when' the same is cold,

and vaporization of the liquid fuel is thereforerelatively less-completethan usual, .If heavier fuels be used in thecarburetei", the

priming valve '20 may be used to admit a lighter and more readilyvaporized fuel,

such as gasolene, to assist in starting the engine when cold. Ihaveherein described and ,illlstltlttll my device in its preferred form, andadapted to be connected in the preferred manner to an internalcombustion engine .of a well known type. It is obvious, however, that mydevice may be connected in other Ways, and that its form may be changedin accordance therewith. i
